Lieberman EG, Hansen EJ, Clohisy JC, et al. - This study was undertaken to investigate patient factors correlated with failure of same-day discharge (SDD) in patients undergoing elective total joint arthroplasty (TJA) in a hospital setting. Between January 31, 2018, and February 1, 2020, researchers retrospectively examined consecutive patients who had undergone primary total knee arthroplasty (TKA) and total hip arthroplasty (THA). They collected patient demographics, co-morbidities, and clinical data. The study was performed to evaluate risk factors for failed SDD. During the study period, 2,615 TJA (1,425 TKA, 1,190 THA) were conducted. It has been reported that the success of SDD was greater than 80%. As per the results, hypotension, delayed resolution of spinal, and nausea accounted for 60% of failures of SDD. The results demonstrated that after THA or TKA, patients > 70 years-old, those with > 2 self-reported drug allergies, or patients who used preoperative narcotics were at high risk for failure of SDD.
